20 Most Recent 1973 Yamaha DT 360 Questions & Answers

If it is the old style fuelcock there is a four hole washer that needed replacement on a yearly basis way back then (poor quality rubber).Just buy the washer that should be all you need unless there is other damage. than replace the assembly. With the age of the machine your only option may be to replace the worn washer as the new assembly is probably no longer available.

Problem could be a few different things. Not sure on all the ignition parts on that bike, but could be a bad sparkplug cap, wire, coil or magneto. My recommendation would be to first take the spark plug cap off. Trim a bit off the wire and put the cap back on. Over time spark plug caps move quite a bit and wear out the wire inside cause a weak connection.

mag wiring is pretty straight forward, if the mag is working properly you just turn it off or on with the ignition switch. if need be track the wire to and from the mag to the switch. you haven't said what your problem is.

In order of precedence, check plug - please try the following:u- New spark plug (this might be fouled)- Check ignition points and gap- Replace condenser- Test / replace coil . Test using continuity meter.. replace if faulty.Let me know how it goes, and if this answer helped. Thank YouNik

I think you will find it to be a 1976. What it is worth is only a rough guess, $400 or so. if it is in running condition. Parts source; www.babbittsonline.com

Could be you have a RT 360 frame, with a DT 360 motor in it. The RT was before the DT. Do some searching on the net for yamaha RT models.

Im a little unsure about your lo and mid air bleeds.
It should have an idle speed screw and an idle mixture screw.
The mixture screw should be set around 1 3\4 turns out from the full in position. The idle speed screw should start at a point where it just starts to lift the carb slide.
make sure the air filter element is clean and there is no wasp nest or blockage in the exhaust , as it has obviously not been used much in 36 years. They always needed a pretty good kick to get them started, Will it roll start ? Also I cant remember if that model had a decompressor valve which may have carboned up
